Mikael, you don't think heat is an issue even though fuel is clearly boiling in the bowls? Fuel should not be boiling and the fact that it is would imply that too much heat is being absorbed at the carb. Rebuilding or replacing the carb won't make it any cooler.
#5754, sorry to hear your problem has reared its head again. I'm interested in following your progress so keep us posted.
To address the heat I've ordered a 1" phenolic spacer from Summit and a 15" oval K&N air cleaner. My current round cleaner barely fits under the rear deck lid as it is so I'm going to have to go to an oval design to accommodate the additional height. I've also ordered a Holley rebuild kit.
Gonna start with cleaning the current needle and seat and checking the floats.
